Might as well fake the normal aliases in soundcore if loaded rather than
pollute chardev with it but otherwise I think we agree.

In the mean time if you are grabbing just some minors sound_core.c:chains
also needs keeping in sync with direct character range grabs because your
CUSE based device might grab some minors before sound_core, and then it
appears tears will result ?
